DESCRIPTION OF COURSES
PL PATH 515 BIOCONTROL OF PLANT DISEASES (2L+1P) II
To provide knowledge on principles, methods, mechanism of bio-control agents and their use against plant diseases
Concept of biological control, definitions, importance, principles of plant disease management with bioagents, history of biological control, merits and demerits of biological control.
Types of biological interactions, competition, mycoparasitism, exploitation for hypovirulence, rhizosphere colonization, competitive saprophytic ability, antibiosis, induced resistance, mycorrhizal associations, operational mechanisms and its relevance in biological control.
Characterization and evaluation of bioagents, case example of successful bioagents (bacterial and fungal bioformulation), variability and characterization of bioagents important characteristics like competitive saprophytic ability, pesticide resistance
Commercial production of antagonists, Improvisation, genetic engineering, delivery systems, application and monitoring, biological control in IDM, IPM and organic farming system, biopesticides available in market. Quality control system of biocontrol agents.
Isolation, characterization and maintenance of antagonists, methods of study of antagonism and antibiosis, application of antagonists against pathogen in vitro and in vivo conditions. Study of cfu/g.
